Re: Handling apostrophes
Hi there, you should simply duplicate in every input string the apostrophe. Meaning that if the input string is: eee'eee after manipulating it - BEFORE inserting it to the DB it will be: eee''eee ( ' twice, NOT A double quote) in the DB it will appear as SINGLE apostrophe. That will work! :o) David. - Original Message - From: [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Monday, October 22, 2001 10:55 AM Subject: Handling apostrophes Hi all, I'm developing an application which uses java servlets and JSPs and a MySQL database running on Tomcat 4.0.

admin context
Hello there, I tried following the instructions of how to manage the admin context in Tomcat 3.2.3, yet could not understand what to do... what is the trusted attribute in the Context tag in server.xml? where do I need to define users? in tomcat-users.xml? which role does the admin have? Please link me to a clear explanation page, or list the actions I should take... :o) Thanks in advance! David.
Re: Handling apostrophes
do you believe that replacement of one char in a string with two chars costs more than encoding the string? David. btw, I believe that prepared statements may solve that issue the best way, that's in case you do not use JdbcOdbcBridge, from my experience I studied that it doesn't update varchar fields properly, make sure it won't happen to you.

please help me to pass that obstacle...
Hi,
I am really tired of that trial and error games... I am trying to have the
Tomcat look for EJB object stored in JBoss application server.
I am using Tomcat and JBoss 2.4.0.
I did the following:
1) added context parameters (the environment variables for JNDI)
context-param
param-namejava.naming.factory.initial/param-name
param-valueorg.jnp.interfaces.NamingContextFactory/param-value
/context-param
context-param
param-namejava.naming.provider.url/param-name
param-valuelocalhost:1099/param-value
/context-param
2) copied all the necessary jars to the WEB-INF\lib folder
3) ejb-ref to the web.xml
ejb-ref
descriptionreference to LoginBean - authenticates user's login and
returns rights level/description
ejb-ref-nameejb/AuthHome/ejb-ref-name
ejb-ref-typeSession/ejb-ref-type
homeauthBean.AuthHome/home
remoteauthBean.Auth/remote
/ejb-ref
4) added the following code to the servlet:
// Set properties
Properties newProps = System.getProperties();
newProps.put (java.naming.factory.initial,
getServletContext().getInitParameter (java.naming.factory.initial));
newProps.put (java.naming.provider.url,
getServletContext().getInitParameter (java.naming.provider.url));
System.setProperties (newProps);
AnEJB gocha = null;
// Obtain a remote reference
try {
InitialContext jndiContext = new InitialContext();
Object ref = jndiContext.lookup(java:comp/ejb/AnEJBHome);
AnEJBHome home = (AnEJBHome) PortableRemoteObject.narrow (ref,
AnEJBHome.class);
gocha = home.create();
}
catch (Exception e) {
System.err.println (An exception occurred while obtaining a remote
reference:);
System.err.println (e.toString());
}
InitialContext ctx = new InitialContext();
Object ref = ctx.lookup(java:comp/ejb/AuthHome); //THIS LINE THROWS AN
ERROR
why this lookup fails?
in the ejb-ref I explicitly typed that the ref-name is ejb/AuthHome.
I know it is a small thing...
What am I missing?
Thanks!
David.

Re: problems serving HTTP requests
Thanks for your reply. The problem is that the ISAPI doesn't seem to pass the request to Tomcat. I know that is the request is for a non existing page there is an error that the Tomcat logs, right? Well, even if I request for a page within the application that does not exist there is no log about it in the Tomcat logs. IIS logs the action to be successful but Tomcat is not activated at all... What could cause that kind of behavior?

update jsp:pluggin (applet type)
Hi, I asked too many people that question, yet no answer... Is there a way to update the auto-generated code to jsp:pluggin for applet type? I am using Tomcat 4 (beta 1) and I my user requiered to have 1.3 pluggin for Java, where can I update that detail? thanks, David.
jsp:pluggin question
Hello everybody,
I have two questions:
1. If I want to update the pluggin version that Tomcat should add to the
HTML code while creating the "OBJECT" tag, how can I do it? (I am talking
about "OBJECT
codebase="http://java.sun.com/products/plugin/1.2.2/jinstall-1_2_2-win.cab#V
ersion=1,2,2,0"").
2. In order to add PARAM to the applet, I need to create jsp:params and
inside jsp:param name="name" value="value"/. Now, my problem is that I
added the param that way but when I try to use it in the applet
(getParameter("name")) I get the following error in the applet console:
"getParameter(Unknown Source)" pointing to the line with getParameter
method. There is no doubt that I used the same name in the applet and in the
jsp page.
Is there any idea what could go wrong with it?
Thanks, David.

adding dynamic content to jsp:param
Hi, I tried to create a page which dynamically will add an id to each user who enters the page, this id should be used by an applet.

Its probably because the String str is not public, only package
access. Tomcat should have complianed and printed out the description of
the error message to the web browser. If you have set up some error
pages,
you might want to comment them out until you get the pages compiling.

I added the instance I created in the first JSP page to the session (
session.setattribute("atr") ), I made sure that session does exist when I
enter the first JSP page. I linked this page to a servlet, created an
instance of the HttpSession and tried to get the str/num of that class:
HttpSession session = request.getSession();
test foo = (test)session.getAttribute("atr");
String lala = foo.str;
out.println("sessionVar: " + lala);
I get an error ("The page cannot be displayed") because of the third line
(when I comment it, the servlet IS found and executed...).
what is wrong???
Thanks in advance!

POST/GET problems
Hi, I recently downloaded Tomcat 4 (b1) from apache site. After installing it I tried to write a servlet to test it's operation. I keep getting the following message from the server: "HTTP Status 405 - HTTP method GET is not supported by this URL. The specified HTTP method is not allowed for the requested resource (HTTP method GET is not supported by this URL). " What could be the problem for that? I defined the mime type (response.setContentType()). I added a new context for my files, could it be the problem? is there anywhere I should define something bout get/post? Thnaks in advance, David Treves. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, email: [EMAIL PROTECTED]
